Abstract

Background: Alexandrite laser is more adapted for lighter hair but not for darker skin, while the Nd:YAG laser is more suitable for darker skin but not for lighter hair.

Objective: To evaluate both laser used as single treatment and in simultaneous emission for axillary hair removal.

Method: Ten patients (18-40 years old) were selected for this study. The spot size and pulse time were kept constant for all patients, 14 mm and 5 ms, respectively. The fluences were 20 to 28 J/cm², 16 to 25 J/cm², and 14-8 J/cm² to 25-13 J/cm² for Nd:YAG, alexandrite and the combined alex/YAG, respectively. Three treatment sessions were performed at 6-week interval, and patients were reviewed 4 months after the last session.

Results: The median number of hairs reduced from 46.00 to 33.00 (p = .022) for alexandrite, from 44.50 to 30.00 (p = .02) for Nd:YAG and from 56.00 to 19.50 (p = .005) for alexandrite-Nd:YAG, equivalent to 46.70%, 27.74% and 70.12% median hair reduction, respectively.

Conclusions: The simultaneous emission of both 755 nm and 1064 nm Nd:YAG laser is significantly more effective than a single laser treatment. Future studies are needed to confirm the good results of this innovative technique.

同时发射波长为 755 nm 的 LP 紫翠宝石和波长为 1064 nm 的 LP Nd:YAG 激光进行腋毛脱除：对两种激光单独使用和双模式使用的前瞻性比较评估。

背景：亚历山大激光更适合浅色毛发，但不适合深色皮肤，而Nd:YAG激光更适合深色皮肤，但不适合浅色毛发：评估两种激光用于腋下脱毛的单次治疗和同时发射的效果：本研究选择了 10 名患者（18-40 岁）。所有患者的光斑大小和脉冲时间保持不变，分别为 14 毫米和 5 毫秒。掺钕钇钕石榴石（Nd:YAG）、翠绿宝石和翠绿宝石/钇钕石榴石联合疗法的能量分别为 20 至 28 J/cm2、16 至 25 J/cm2、14-8 J/cm2 至 25-13 J/cm2。每隔 6 周进行三次治疗，最后一次治疗后 4 个月对患者进行复查：结果：翠绿宝石的毛发数量中位数从 46.00 根减少到 33.00 根（p = .022），Nd:YAG 的毛发数量中位数从 44.50 根减少到 30.00 根（p = .02），翠绿宝石-Nd:YAG 的毛发数量中位数从 56.00 根减少到 19.50 根（p = .005），相当于毛发数量中位数分别减少了 46.70%、27.74% 和 70.12%：结论：同时发射 755 纳米和 1064 纳米 Nd:YAG 激光的效果明显优于单一激光治疗。未来的研究需要证实这一创新技术的良好效果。
